Imax Power Smart Low-Voltage Hybrid Cabinet: Enabling Safe and Efficient New Energy Grid Integration
Driven by “dual carbon” goals, new energy installations surge. Achieving safe grid integration, efficient management, and stable power supply for multi-energy complementary systems is critical. Imax Power’s smart low-voltage hybrid cabinet leverages “functional integration, professional protection, and adaptive flexibility” to deliver end-to-end solutions for PV, wind, and other new energy systems, redefining value standards for low-voltage grid-tied equipment.
I. Technical Core: Multi-Functional Integrated “Smart Hub”
Imax Power’s cabinet achieves deep integration of AC confluence, bidirectional metering, and grid-switching functions via modular design and intelligent algorithms. Its technical principles unfold in three tiers:
1. AC Confluence Layer
- Multi-channel AC confluence modules support current integration from PV inverters, wind turbines, and energy storage systems, reducing line losses and equipment footprint.
Example: In a 10MW PV plant, Imax Power’s cabinet reduces DC cable usage by 30%, boosting system efficiency by 2%.
2. Bidirectional Metering Layer
- High-precision energy meters enable bidirectional power measurement (error <0.5%), providing data for peak-shaving optimization and energy trading.
3. Intelligent Control Layer
- DSP-based digital signal processors monitor voltage, frequency, and harmonics in real-time, automatically adjusting grid-tied strategies to comply with IEEE 1547 and other international standards.
II. Product Strengths: Six Advantages of an All-Round Solution
1. Comprehensive Function Integration, Doubled Space Efficiency
- Combines AC confluence, bidirectional metering, reactive compensation, and protection in one unit. Replaces traditional multi-cabinet setups, reducing footprint by 50%. Ideal for space-constrained rooftop PV and industrial parks.
2. Stable Power Supply, Reliable Load Support
- Dual-power switching design ensures seamless transfer to backup power (e.g., energy storage systems) within 0.1 seconds during mains failures. Annual availability exceeds 99.99% for critical loads like hospitals and data centers.
3. Premium Components, Robust Reliability
- Core components (circuit breakers, contactors, sensors) sourced from Schneider, ABB, and Siemens pass 100,000+ mechanical endurance tests and operate in -40°C~+70°C environments.
4. Superior Protection, Harsh Environment Adaptability
- IP55-rated enclosure with dust/water resistance withstands sandstorms, heavy rain, and extreme temperatures. In Gansu’s desert PV project, the cabinet endured 12 typhoon-level sandstorms with zero failures.
5. Multi-Layer Safety Defenses
- Integrates overcurrent, overvoltage, undervoltage, and leakage protection. Arc-fault protection and rapid grounding switches ensure response times <10ms.
6. Broad New Energy Compatibility
- Supports PV, wind, storage, and diesel generators. Adaptive algorithms smooth power fluctuations caused by intermittent renewable generation.
III. Applications: From Industrial Parks to Microgrids
1. Industrial-Commercial Distributed PV
- For a car factory in Jiangsu, the cabinet’s “8-in-1” confluence design boosted self-consumption by 40%, saving >¥2 million annually in electricity costs.
2. New Energy Microgrids
- In Hainan’s island microgrid project, seamless switching between PV/wind and storage achieved 99.9% reliability, displacing diesel generation and reducing CO₂ by 1,200 tons/year.
3. PV-Storage-Charging Integrated Stations
- At a Beijing fast-charging station, dynamic adjustment of PV-storage output stabilized the grid. Total Harmonic Distortion (THD) dropped from 8% to 3%, extending equipment lifespan by 30%.
